AUTOMATIC OILER.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed. October 4, 1919. Serial No. 328,376.

To aZZw/wm it may concern:

Be it known that I, RAYMOND G. Freon, citizen of the United Statesresiding at Cleveland, in the county of (/uyahoga and State of Ohio,have invented certain new and useful Improvements in Automatic Oilers,of which the following is a specification.

This invention relates to an oiling device which will be automatic inits action and is particularly adapted for use in lubricating thevarious running parts of an automobile, such as the cooling fan, thespring shackle bolts, and the various levers and connecting links whichdue to their frequent use require a constant supply of lubricant.Although it is obvious that an apparatus of like character may beapplied to any moving part of machinery.

The invention consists in the construction, combination and novelarrangement of parts as hereafter shown, described and specificallypointed out in the appended claim.

Referring to the drawings wherein like reference numerals designatesimilar parts of reference throughout the various views, Figure 1 is anelevation of the device constructed in accordance with the principlesabove set forth; Fig. 2 is a central vertical section through the deviceand Fig. 3 is a plan view thereof.

The lubricator as shown comprises a cylindrical reservoir 1 which isprovided near its top and bottom with annular beads 2 which are pressedoutwardly from the metal and which serve to strengthen the reservoir andprevent injury thereof. The reservoir is closed with a bottom 3 and thetop is closed with a cap or cover 4:, and this cover may be permanentlyfixed to the reservoir if desired, although it is not necessary be causeof its frictional engagement thereof. The central portion of the coveris in the form of an inverted cone and at the apex thereof is providedwith a semi-spherical projection 5 for a purpose to be hereinafterdescribed.

Oil is fed into the reservoir through an opening 6 which is normallykept in a closed position by means of a pivoted cover 7. The oil. is feddownwardly to the working parts by means of a conveying pipe 8, whichproj ects through a suitable opening in the bot tom 3 of the reservoirand is secured in place by having the metal of which the bottom is madebent or crimped, as shown at 9, over an annular flange 10 formed as partof the pipe 8. Beneath the flange l0 and projecting outwardly from thereservoir the pipe is provided with a tapered thread 11 whereby asuitable connection 12 may be screwed to convey the oil to the workingparts of the machinery.

The manner in which the oil is conveyed there may be briefly describedby the following:

Oil is supplied to the reservoir through the opening 6 until such timeas the level thereof approaches the top of the reservoir. Due to thefact that the machine is in motion the oil is agitated sufficiently tobathe the under surface of the inverted cone portion of the cover 1-,and the oil then gravitates to the center or apex thereof and collectsupon the spherical projection 5, and sufficient oil accumulating thereit drops into the'frusto-conical opening 13 in the top of the pipe andis conveyed downwardly through the reduced bore 14 of the pipe. Thisbore extends approximately to the bottom of the reservoir and isenlarged as shown at 15 and permits the same to be conveniently cleaned,and from there the oil is conducted directly to the'working parts of themachinery.

It will thus be seen that an automatic means is provided whereby oil maybe fed in an economical and effective manner to the machine in apositive manner, by a device that will need a minimum of attention onthe part of the user and one which is incapable of becoming clogged,thereby impairing its efficiency.

While I have shown and described this particular form of invention I donot wish to limit myself in the construction of the same further than isrequired by the state of the art or that which comes within the scope ofthe appended claim.

I claim:

An oil cup provided with an outlet pipe having an upper open end withinthe cup and above the normal oil level therein, and an inverted conicalcap on the cup, said. cap having a projection at its apex above the openend of said pipe, and also having a filling opening provided with acover, located out of alinement with said pipe.

In testimony whereof, I do affix my signature in presence of twowitnesses.
